/* ============================================================
   Language switcher widget — shared between landing & dashboard.
   The widget reads CSS variables that BOTH pages already define
   (--text, --text-muted, --secondary, --tertiary, --border,
   --bg-secondary, etc.) so no theme overrides are needed.
   Falls back to hardcoded values for any var not defined.
